Specification of Letters Patent.

` Patented June 30, 1914.

Application filed January '18, 1913. Serial No. 742,864,

To all whom it may concern Be it known that I, ROBERT A. GALLY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Music-Roll-Propelling Systems, of which the following is a specification.

Previous attempt-s in placing a motor and connections therefrom to the music-roll propelling devices, in a player piano of horizontal form, as a grand, have required enlarged cases, and have been of complicated structure and inconvenient of access, where the present invention causes no enlargement of the' piano, and has a minimum of parts that are direct in action and readily reached.

In the drawings, Figure 1 is a plan view of a grand piano with parts of the plate and sound-board and wrest plank removed to show the motor and shaft, Fig. 2 is a front view of the same, and Fig. 3 a view of the sprocket wheels, etc., as seen from the right end of Fig. 2.

The grand piano shown has a case comprising a rim 1 and a cross-rail 2, with braces 3, 4 and 5 extending rearwardly from said cross-rail 2 to said rim 1. A wrest plank 6 extends` across the piano and the metal plate 7 is fastened on its top. Tuning pins 8 are provided for attachment ofthe strings 9. In front of the wrest plank is a front rail 10. A motor 11 at rear of crossrail 2 has its shaft 12 in a line at right angles to the cross-rail 2 and front rail 10, and a separable coupling 13 connects it with a main shaft 14 which continues forward through a hole 15 in cross-rail 2 to a miter gear 16 attached on its front end, where the shaft 14 is supported in a bearing 17. Bearing 17 also supports a drive shaft 18 at right angles to shaft 14, on which shaft 18 is mounted a miter gear 19 which is in running engagement with its mate gear 16. Drive shaft 18 lies somewhat under the wrestplank 6 and parallel with front rail 10. On drive-shaft 18 is a pinion 2O engaging a gear 21 connected with take-up spool 22, and farther along the drive shaft 18 is a sprocket wheel 28 or equivalent drive connected by a chain-belt 24 or equivalent to a wheel or gear 25 on a counter-shaft 26 which runs to reroll a music sheet from take-up spool 22. Chain 24 or other transmission means passes through hole 27 in wrest-plank 6.and pla-te 7, forward and clear of tuning pins 8.

The loosening of miter-gear 19 on driveshaft 18 as by a set screw 30 enables the sliding of shaft 18 out of gear 19 and bearing 17 and the removal of shaft 18 and its connected parts from the piano without disturbing main-shaft 14. Drive-shaft 18 may be carried by a frame 29 which also has the take-up spool 22 and other related parts carried by it, so all said parts may be removed as a unit.

The usual means may be employed for shifting the pinions and wheels for alternate forward or reroll drive, or modifications made herefrom, and yet be what I claim as my invention. i

Claims:

1. A horizontal player piano having a cross-rail, a motor having a shaft lying rearward of and at a right angle to said crossrail, a hole in said cross-rail, and a continuation of said shaft exgtended forwardly through said hole and having the same axis" as said motor-shaft.

2. A horizontal player piano having a cross-rail, a motor having a shaft lying rearward of and at a right angle to said crossrail, a hole in said cross-rail, and a continuation of said shaft extended forwardly through said pole and having the same axis as said motor-shaft, and a separable coupling connected to both said shafts at their meeting place.

3. A horizont-al player piano having a cross-rail, a motor having a shaft lying rearward of and at a right angle to said crossrail, a hole in said cross-rail, and a continuation of said shaft extended forwardly through said hole and having the same axis as said motor-shaft, a drive-shaft disposed at a right angle to the main-shaft at the forward end of said main-shaft, and miter gear connections from one shaft to the other at their meeting place.

4. A horizontal player piano having a rim, a cross-rail, and braces extended rearwardly from said cross-rail to said rim, a motor disposed at the rear of said rail and in the space between the rim and the next adjacent brace, and a main-shaft extending from said motor through and forward of said cross-rail.

A horizontal player piano having a rim, a cross-rail, and braces extended rearwardly from Said cross-rail to said rim, a motor disposed at the rear of said rail and in the space between the rini and the next adjacent brace, and a main-shaft extending frein said inotor through and forward of said cross-rail, and a drive-shaft disposed at a right angle to the main-shaft at the forward end of said main-shaft and initergear connections from one shaft to the other at their nieeting place.

6. A horizontal player piano having a rim, and wrest plank and a Yfront-rail substantially at a rightI angle to said rini, a shaft bearing affixed to the inner part of said rini adjacent said front rail and under said wrest-plank, a shaft engaged in said hearing and extended rearwardly thereof, and another shaft engaged in said hearing and extended therefrom at a right angle to said irst nained shaft, and under and parallel with the front and under faces of said front rail.

7. A horizontal player piano having a riin, a wrest plank and front-.rail substantially at a right angle to said riin, a shaft bearing affixed to the inner part of said riin adjacent said front rail and under Said wrest-plank, a shaft engaged in said hearin g and extended rearwardly thereof, and another shat't engaged in said hearing and eX- tended therefrom at a right angle to said first nained shaft, and initer-gears connected to said shafts adjacent said hearing and engaging one with the other.

8. A player piano having a horizontal l wrest-plank, and a inetal plate and pins and strings thereon; a drive-shaft disposed horizontally under said wrest-plank and. parallel to its front line; a counter-shaft above said plate and wrest-plank, and parallel their front lines; driif'e-ineans on each Said shaft; a hole in. said plate and wrest-plank in line with the tvvo said drive nieans; and transinission ineans extended through said hole from one said drive means to the other.

9.151. player piano having a horizontal winst-plank, and a inetal plate and pins and strings thereon; a drive-shaft disposed horizontally under said wrest-plank and parallel to its front line; a counter-shaft above said plate and dest-plank, and par allel their 'trent lines; drive-means on each said shaft; a hole in said plate and wrestplank in line with the two said drive means and toi-ward ol seine ot' said pins.

l0. A player piano having a horizontal wrest-plank, and a inetal plate and pins and strings thereon; a drive-shaft disposed horizontally nn der said wrest-plank and parallel to its liront line; a counter-shaft above said plate and vfrest plank, and parallel their front lines; drive-means on each said shaft; a hole in said plate and wrest-plank in line with the two said drive ineans and forward ot seine oli-said pins, and nearer the middle l' ot the piano than others of said pins.
